Webinar, Part Ii: Four Types Of Cyclists: A National Look, Jennifer Dill

TREC Webinar Series

Originally developed by Roger Geller for the city of Portland, the "Four Types of Cyclists" typology (Strong and Fearless; Enthused and Confident; Interested but Concerned; No Way No How) has been adopted widely to help guide efforts to increase bicycling for transportation. This webinar will present findings from a new, national survey conducted in collaboration with the National Association of Realtors. We will address the following questions:

• Does the Four Types of Cyclists typology apply nationally?
• What are the characteristics of each type of cyclist?
• How does the existing environment, including bicycle infrastructure, affect the share of people in each …

Webinar, Part I: Americans' Views Of Transportation And Livable Communities, Jennifer Dill, Hugh Morris

TREC Webinar Series

The National Association of Realtors® and Portland State University conducted a nationwide survey in the 50 largest metropolitan areas, asking Americans about where they live, where they want to live, and their travel habits.

This webinar will present the key findings from that survey, including people’s preferences to live in mixed-use, walkable communities and what may help them walk, bicycle, and take transit more. The large sample (3,000) allows us to look at demographic differences, including between the generations (Millennials, Baby Boomers, etc.).

Neighborhood Crime And Transit Station Access Mode Choice - Phase Iii Of Neighborhood Crime And Travel Behavior, Christopher E. Ferrell, Shishir Mathur, Bruce S. Appleyard

Mineta Transportation Institute

This report provides the findings from the third phase of a three-part study about the influences of neighborhood crimes on travel mode choice. While previous phases found evidence that high levels of neighborhood crime discourage people from choosing to walk, bicycle and ride transit, consistent with the authors’ hypothesis, they also produced counterintuitive findings suggesting that in some cases, high crime neighborhoods encourage transit ridership at the expense of driving—the opposite of what common sense would suggest. Phase 3 tested possible explanations for these counterintuitive findings with a series of methodological improvements. These improvements were:

• Improvement 1: Used the Bay …

Advanced Low-Floor Vehicle (Alfv) Specification Research, Suresh Iyer, Partha Mishra, David Klinikowski, Boyd Thompson, Myra Strange, Wanda Boggs, Carl Thornblad

Mineta Transportation Institute

This report details the results of research on market comparison, operational cost efficiencies, and prototype tests conducted on a novel design for an Advanced Low Floor Vehicle (ALFV), flex-route transit bus. Section I describes how the need for such a bus arises from a combination of diminishing transit funding from the federal government and demographic and transportation factors. Section II describes the unique features of this bus design that render it suitable for rural and urban operation, including improved transit passenger and wheelchair accessibility, reduced maintenance, structural design features, safety provisions, and the technical specifications of this design. Section III …

Cooperation In Delay-Tolerant Networks With Wireless Energy Transfer: Performance Analysis And Optimization, Dusit Niyato, Ping Wang, Hwee-Pink Tan, Walid Saad, Dong In Kim

Research Collection School Of Computing and Information Systems

We consider a delay-tolerant network (DTN) whose mobile nodes are assigned to collect packets from data sources and deliver them to a sink (i.e., a gateway). Each mobile node operates by using energy transferred wirelessly from the gateway. For such a network, two main issues are studied. First, when a mobile node is at the data source, this node must decide on whether to accept the packet received from the data source or not. In contrast, whenever a mobile node is at the gateway, it has to decide on whether to transmit the packets collected from the data sources or …

On Mining Lifestyles From User Trip Data, Meng-Fen Chiang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Large cities today are facing major challenges in planning and policy formulation to keep their growth sustainable. In this paper, we aim to gain useful insights about people living in a city by developing novel models to mine user lifestyles represented by the users' activity centers. Two models, namely ACMM and ACHMM, have been developed to learn the activity centers of each user using a large dataset of bus and subway train trips performed by passengers in Singapore. We show that ACHMM and ACMM yield similar accuracies in location prediction task. We also propose methods to automatically predict "home", "work" …

Improved Safety Performance Functions For Signalized Intersections, Karen Dixon, Christopher Monsere, Raul Avelar, Joel Stephen Barnett, Paty Escobar, Sirisha Murthy Kothuri

Civil and Environmental Engineering Faculty Publications and Presentations

For this effort, the research team developed new safety performance functions (SPFs) for signalized intersections in Oregon. The modeling dataset consisted of 964 crashes from a total of 73 intersections that were randomly selected based on the presence of a traffic signal (identified through the crash data records). The SPFs were developed using a Poissonlognormal Generalized Linear Mixed model framework for total crashes and severe injury crashes (coded as KAB). Three SPFs were developed: 1) an SPF for total crashes, which relies on both major and minor AADTs to predict the expected number of crashes; 2) an SPF for KAB …

Development Of Bus-Stop Time Models In Dense Urban Areas: A Case Study In Washington Dc, Stephen Arhin, Errol Noel

Mineta Transportation Institute

Bus transit reliability depends on several factors including the route of travel, traffic conditions, time of day, and conditions at the bus stops along the route. The number of passengers alighting or boarding, fare payment method, dwell time (DT), and the location of the bus stop also affect the overall reliability of bus transit service. This study defines a new variable, Total Bus Stop Time (TBST) which includes DT and the time it takes a bus to safely maneuver into a bus stop and the re-entering the main traffic stream. It is thought that, if the TBST is minimized at …

Robust Observability, Control, & Economics Of Complex Cyber-Physical Networks, Shaurya Agarwal

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation deals with various aspects of cyber-physical system. As an example of cyber physical systems, we take transportation networks and solve various problems, namely: 1) Network Observability Problem, 2) Network Control Problem, and 3) Network Economics Problem. We have divided the dissertation into three parts which solve these three problems separately. First part of the dissertation presents a novel approach for studying the observability problem on a general network topology of a traffic network. We develop a new framework which investigates observability in terms of flow information on arcs and the routing information. Second part of the dissertation presents …

Promoting Intermodal Connectivity At California’S High-Speed Rail Stations, Anastasia Loukaitou-Sideris, Deike Peters, Wenbin Wei

Mineta Transportation Institute

High-speed rail (HSR) has emerged as one of the most revolutionary and transformative transportation technologies, having a profound impact on urban-regional accessibility and inter-city travel across Europe, Japan, and more recently China and other Asian countries. One of HSR’s biggest advantages over air travel is that it offers passengers a one-seat ride into the center of major cities, eliminating time-consuming airport transfers and wait times, and providing ample opportunities for intermodal transfers at these locales. Thus, HSR passengers are typically able to arrive at stations that are only a short walk away from central business districts and major tourist attractions, …

The Benefits Of Transit In The United States: A Review And Analysis Of Benefit-Cost Studies, Christopher E. Ferrell

Mineta Transportation Institute

This white paper presents the findings from a review and analysis of the available literature on benefit-cost (b-c) estimates of existing U.S. transit systems. Following an inventory of the literature, the b-c estimates from each study were organized according to the type of study area (e.g., rural, small urban, urban, etc.). Through this process, categories of monetary transit benefits were identified. The estimated dollar value for each benefit category was divided by the total estimated costs of providing the transit services, thus creating a benefit-specific b-c ratio for each category and allowing benefits from each study to be compared on …

Using Visual Data Mining In Highway Traffic Safety Analysis And Decision Making, Yao-Te Tsai, Huw D. Smith, Stephen M. Swartz, Fadel M. Megahed

Journal of Transportation Management

An ongoing, two-fold challenge involves extracting useful information from the massive amounts of highway crash data and explaining complicated statistical models to inform the public about highway safety. Highway safety is critical to the trucking industry and highway funding policy. One method to analyze complex data is through the application of visual data mining tools. In this paper, we address the following three questions: a) what existing data visualization tools can assist with highway safety theory development and in policy-making?; b) can visual data mining uncover unknown relationships to inform the development of theory or practice? and c) can a …
